Engineering Selection Recommendations

CM05FD161JO3 (Original Part): This part is suitable for applications where RoHS compliance is not a requirement and REACH-affected material usage is acceptable. The part maintains active status with established supply availability.

CD15FD161JO3 (Substitute - RoHS Non-Compliant): This substitute provides identical electrical and mechanical performance to the CM05FD161JO3. It represents a product line transition within the CDE portfolio. Selection is appropriate for applications with equivalent compliance requirements to the original part. Higher inventory availability (1372 pcs) supports supply chain continuity.

CD15FD161JO3F (Substitute - RoHS3 Compliant): This substitute meets all electrical and mechanical requirements of the CM05FD161JO3 while providing ROHS3 compliance and REACH unaffected status. Selection is required for applications subject to RoHS3 regulations or REACH material restrictions. This variant is the preferred choice for new designs or applications with environmental compliance mandates.

All three parts are manufactured by Cornell Dubilier Electronics and share identical electrical performance, mechanical compatibility, and environmental operating specifications.

Frequently Asked Questions (FAQ)

Q: Can CD15FD161JO3 and CD15FD161JO3F be used interchangeably with CM05FD161JO3?

A: Yes. Both substitute parts meet all electrical parameters (160 pF, ±5%, 500 V), mechanical specifications (radial through-hole, 0.232" lead spacing, identical dimensions), and environmental operating range (-55°C to 125°C). Direct substitution is electrically and mechanically valid.

Q: What is the difference between CD15FD161JO3 and CD15FD161JO3F?

A: The primary difference is regulatory compliance. CD15FD161JO3F is ROHS3 compliant and REACH unaffected, while CD15FD161JO3 is RoHS non-compliant and REACH affected. Both parts are electrically and mechanically identical. Selection depends on application compliance requirements.

Q: Are there any physical differences between these parts?

A: No. All three parts share identical physical dimensions (0.461" L x 0.189" W), height (0.370" max seated), and lead spacing (0.232"). They are mechanically interchangeable in PCB layouts and through-hole mounting applications.

Q: Which part should be selected for new designs?

A: CD15FD161JO3F is the recommended selection for new designs due to ROHS3 compliance and REACH unaffected status, ensuring long-term regulatory alignment and supply chain sustainability.

Q: Is there a difference in electrical performance between the three parts?

A: No. All three parts deliver identical electrical performance: 160 pF capacitance at ±5% tolerance, 500 V voltage rating, mica dielectric, and -55°C to 125°C operating temperature range.

Q: Can these parts be used in high-frequency applications?

A: Mica capacitors are suitable for general-purpose applications across the specified operating temperature range. Application-specific frequency performance must be evaluated against detailed frequency response data from the manufacturer's technical documentation.
